The invention relates to amachinfor attaching buttons to slices andother articles by metallic fasteners, and 1s especially 1ntended forthat class ofl such vmachines in which themetallic fastener' formed froma Wire which is fed through the eyeoxl' the button, theivire then beingformed into'the shape for the fastener, the button and at- `tached wirethen being carried to position .forjtlie fastener to be secured to theshoe or other article.

The invention relates especiallyl to means for pushing or removing thebuttons from the raceway one` at a time tothe position Where it receivesthe wire through the eye lofthe button and to the means for holding thebutton in position while it is being threaded.

rlhe invention will be fully understood from the following description'taken in connectionV with the accompanying drawings, and thel novelfeatures thereof will be pointed-out and clearly defined in the claimsat the close of this specification.

Referring now to the drawings: 1 represents the racewayl and 2 theraceway cover, the buttons traveling down the raceway with the eyes ofthe buttons in the groove of the raceway in the usual manner. Anysuitable form of mechanism for feeding the wire through the eye of thebutton and 4forming the loop and legs of 'the fastener andsevering theblank for the fastener from the length of wire may be employed,' oneform of said mechanism being shown and described in Patent No. 982,440,dated AJanuary 211, 1911, granted on my applica tion, and itis notdeemed necessary to show such mechanism in detail. In the accom-ypanying(drawings of the present application a portion ofthe mechanismfor forming the fastener is shown similar to the mechanism shown insaid. patent.

3 is an arbor on which the Wire 4 rests after it. has been threadedthrough the eye of the button 6.

is what is termed the former which forms the loop 'of the fastener andis attached to a former holder 8 which is r'eciprocated byan arm 9carried by a lever 10 which is actuated by suitable mechanism, notshown, said arm 9 engaging with a slot 11 in the former holder. The legsof the fastener are formed by a slide12 which is lactuated by an arm 13carriedby a lever 14, said arm 13 engaging with an elongated slot 15 inthe slide 12. Means for actuating said levers 10and 14 is fully shownand described in said patent above mentioned.

l/Vhen the button is in the position for re ceiving the vvire for thefastener, shown in Fig.- 1, ,meanst should be provided for holding thebutt-on against movement during the feeding of the Wire and forming ofVthe fasteners-Themeans which l have provided are as follows: A plate or'block 16 is formed with a cupped out under side which is adaptedto fitover the head of the button andis mounted on a reciprocable or movablerod 17 which may be moved down toclamp the button at the proper time andwhich may be' lifted to release the button after the fastener is formed.Said rod 17 is connectedtivith a lever 18 lwhich is actuated and con died in the manner to be hereinafter-.de Said lever 18 is pivoted at 19.t"1a, nld part of the machine!M Inthe form ivf-:construction shown thelowe;

end of theldverj isbifurc'ated vertically to t-he head Ot the button.

straddle a block 57 which is loose on the rod 17 and is also laterallybiurcated forming ears between which a pin 20 projects from both sidesof the block 57 to engage with the said ears and form a connection withthe said lever 18. The elongated recess 21 between the ears 22-22 allowsplay for the pins 2O during the rocking movement of the lever 18. Aspring 23 coiled around the rod 17 between the block 57 and the placerblock 16 enables the lever 18 to move the placer down with a yieldingpressure upon the button. A slidable push rod 2st is mounted in andslidable in an apertured bracket 25 allixed to the frame ot the ma'chine in such manner that said push rod 24 is inclined at an angle tothe raceway and is adapted to be projected down through the slottedforward end of the cover 2 to engage with the head of a button in thelower part of the raceway and to push it out of the raceway beneath theplacer 16. A finger 2G pivoted at Q7 projects through the cover of theraceway to prevent the button from sliding out of the raceway of its ownweight, being given sui'licient tension for that purpose by a spring 28which yields, however, so that the finger may'be turned upward out ofthe path of the button by the pressure of' the push rod 24 when the pushrod 211 is actuated.

When the parts are in the position shown in Fig. 1 with the former andformer holder Sretracted, the bent rear arm of the lever 18 rests uponthe upper face of the former holder 8, thereby holding .the lever. 18 inposition' where its forward end is turned down to hold the placer inengagement with Villen the former and former holder move down to theposition shown in Fig. Q the former holder rides down out of engagementwith the rear arm of the lever 18 allowing said lever to be turned onits pivot by the spring 4.5, lifting the lower arm of the lever andturning down the rear arm of the lever, as shown in Fig. 2.

A lever 29 pivoted at 30 and is bifurcated forming a. slot 31 with whicha pin 32 projecting from the slide rodQll engages.

Said lever 29 is formed with an elongated slot 33 with which thereengages a pin 34 which projects from a slide bar 35 so that when saidslide bar 35 is moved either torward or baci; ity rocks said lever 29and thereby actuates the push rod 2l. Said slide bar 35 is formed withan elongated slot 36 with which a guide pin 37 engagesto guide and limitthe movementof said slide bar.

A spring 38 has one .end secured to the lower end of the slide bar 35,the other end of said spring beingsecured vto a lined support 39, saidspring normally tending te retain the slide bar 35 in the most forwardposi ion shown in Fig. 2 with the stud 87 engaging the rear end of theslot 36. 'When Losasazi said slide bar is moved backward it expands thespring 38, as shown in Fig. 1 and when the backward pull or detent uponthe slide har is released said spring 38 will pull the slide bar 35forward again.

, A dog 40 is pivoted at 41 to the slide bar 35 and is formed with atooth L12. Said dog is formed with a curved slot 43 with which a pin141. which projects from the side ot the raceway engages. he form of theslot is such that when the slide bar 35 is in its rearinost position,shown in Fig. 1, the dog l() may be turned up with its tooth L12 bearingagainst theupper face or the former holder 8. A spring 45 has its lowerend secured to the frame and its upper end secured to the lever 18 whichexerts a downward pull on the rear arm of the lever 18 and when theformer holder 8 moves downward far enough for the 'former .holder toride out from under the rear arm Vof the lever 18 said spring will pullthe rear arm or said lever 18 down, thereby turning said lever-on itspivot and raising the forward end of said lever and therelr7 raising theplacer 16. 'lVhen the former holder continues itsdownward movement farenough to ride past the tooth 42 then the spring 38 will be permitted topull the slide 35 downward thereby causing'the dog l0 to i he turneddown into the position shown inA Fig. 2 by reason of the pin le/lengagingwith the curved slot i3 and thus bring the tooth 112 of the dogdown behind the rear end ot' the former holder 8, as shown in Fig. 2.1When the slide 35 thus movesdownward it turns the lever 29backwardthereby retracting the push rod 2e, as previously described',the placer 16 being still in the raised position. lVhen the formerholder 8 and its attached former 7 move rearward or up fard, as we termit, the rear end of the 'former by its engagement with the tooth l2 willturn the dog fr0 up on its pivot and also cause the retraction of theslide 85 until the tooth 42 rides up onto the upper side of the formerholder 8 after which the continued rearward movement ci the 'former willict-"further move the slide During said initial rearward movement of.the former and the rearward movement or" the slide 35 the lever 9.9 willbe turned down thereby pushing forward the rod which in so doing willpush forward the button which had previouslyslidden down the racewayinto position beneath the -lorward end of the push rod and in.engagement with the detent QG. This downward push movement of the rod Qdwill be sutlicient to overcome the tension of the detent 2S and push thebutton into position beneath the placer 16.
